FIG. 1 is a perspective view of a display apparatus, according to anembodiment of the disclosure, where a mobile device is held by a holdingdevice.

Referring to FIG. 1, a display apparatus 1 may include a display module10 for displaying a screen, a supporting device 20 coupled to the rearof the display module 10 for supporting the display module 10, and aholding device 100 coupled to the display module 10 to hold a mobiledevice 2.

The display module 10 may be a device for displaying information,materials, data, etc., in characters, figures, graphs, images, etc., andmay include a television, a monitor, etc.

The display module 10 may be configured to display a screen 11. Thedisplay module 10 may include an actively light-emitting display panel(not shown) such as Organic Light Emitting Diodes (OLEDs) or a passivelylight-emitting display panel (not shown) such as Liquid Crystal Displays(LCDs). There are no particular limitations on the type of displaypanel.

The display module 10 may be provided to have different vertical andhorizontal lengths. That is, the display module 10 may have longer sidesand shorter sides. The display module 10 may be shaped like arectangular plate.

The supporting device 20 may be coupled to the rear of the displaymodule 10 for supporting the display module 10. The supporting device 20may include a supporting body 21 coupled to the display module 10, and astand 22 coupled to the rear of the supporting body 21. The supportingdevice 20 may stand by itself with the supporting body 21 and the stand22 each contacting the ground.

The supporting device 20 may include a speaker 30 (FIG. 2) provided toproduce sounds. The speaker 30 may be arranged inside the supportingbody 21. Specifically, the speaker 30 may be arranged in a lower portionwithin the supporting body 21. The speaker 30 may output a sound with animage displayed in the display module 10. Alternatively, the speaker 30may output a sound alone even when the display module 10 is powered off.Furthermore, the speaker 30 may be wiredly or wirelessly connected to anexternal device such as the mobile device 2 for outputting a song playedby the external device.

The holding device 100 may be provided to hold the mobile device 2 to bemounted on the display module 10. The holding device 100 may bedetachably coupled to the display module 10. The holding device 100 maybe coupled to or decoupled from the display module 10 without any extramember.

The mobile device 2 is a kind of external device, including e.g., asmart phone. Mobile devices are widespread these days, and there areattempts to use mobile devices in various ways. Mirroring by whichimages and sounds presented in the mobile device 2 are output throughthe display module 10 or casting by which only content output from aparticular application of the mobile device 2 is output through thedisplay module 10, are typical examples. To utilize such mirroring orcasting, the mobile device 2 and the display apparatus 2 need to bepaired first. According to the disclosure, the mobile device 2 and thedisplay apparatus 1 may be paired using various methods, which will bedescribed later.

More and more people create contents by taking selfies with camerasthese days. It is also more common for people to check their own motionswith their cameras when they practice dancing or doing exercises. Assuch, there are growing needs of users for a mirror mode that uses thecamera and the display screen like a mirror. To provide the mirror mode,however, a camera needs to be installed in the display apparatus, whichcauses concern over privacy invasion and security issues. Furthermore,the rising expenses due to the installation of the camera may lower thesalability of the display apparatus.

According to the disclosure, without installing any camera in thedisplay apparatus 1, the display apparatus 1 may provide the mirrormode. For this, the display apparatus 1 may include the holding device100. The display apparatus 1 may provide the mirror mode by being pairedwith the mobile device 2 equipped with a camera module (not shown) putonto the holding apparatus 100. The mobile device 2 commonly includesthe camera module, so the display apparatus 1 may provide the mirrormode by using the camera module of the mobile device 2. In this way,using a camera module of an external device such as the mobile device 2,the rise in expenses of camera installation in the display apparatus 1may be prevented. Furthermore, the mobile device 2 may be used whenrequired by putting the mobile device 2 onto the holding device 100, sothe privacy invasion or security issues due to the display device 1 mayalso be prevented.

According to the disclosure, the holding device 100 may hold the mobiledevice 2 while the mobile device 2 is placed outside the display module10. Furthermore, the holding device 100 may hold the mobile device 2 notto cover the front or rear surface of the mobile device 2. In otherwords, when the mobile device 2 is put onto the holding device 100, adisplay, the front of the mobile device 2 may not be hidden by theholding device 100. Accordingly, the user may be able to make touchinputs through the display of the mobile device 2 while putting themobile device 2 onto the holding device 100. The user may also use acamera module placed on the front of the mobile device 2 or a cameramodule placed on the rear of the mobile device 2 while putting themobile device 2 onto the holding device 100.

FIG. 2 is a front view of a display apparatus, according to anembodiment of the disclosure, where a display module is positionedlengthwise. FIG. 3 is a front view of a display apparatus, according toan embodiment of the disclosure, where a display module is positionedwidthwise.

Referring to FIG. 2, the display module 10 may have the longer sidespositioned lengthwise and the shorter sides positioned widthwise. Thispositioning of the display module 10 is hereinafter called lengthwisemode. It is also said that the display module 10 is positioned in afirst position.

Referring to FIG. 3, the display module 10 may have the longer sidespositioned widthwise and the shorter sides positioned lengthwise. Thispositioning of the display module 10 is hereinafter called widthwisemode. It is also said that the display module 10 is positioned in asecond position.

The user may selectively place the display module 10 in the lengthwisemode or widthwise mode depending on a screen ratio of an image.

It is common for the conventional display module to be fixed widthwise.In this case, when the conventional display module displays a lengthwiseimage, either side of the screen is blanked, making it impossible toefficiently use the screen of the display module. The lengthwise imageand the widthwise image both tend to be used these days, so there is aneed for a display apparatus capable of displaying various screen ratiosin efficient ways.

In an embodiment of the disclosure, the display apparatus 1 may allowthe display module 10 to be positioned in the lengthwise mode to displaya lengthwise image and in the widthwise mode to display a widthwiseimage, thereby efficiently using a screen display region 11.Accordingly, the display apparatus 1 in accordance with the disclosuremay efficiently present various screen ratios.

In an embodiment of the disclosure, the display apparatus 1 may includethe display module 10 and the supporting device 20 for supporting thedisplay module 10 to be automatically turned by a motor (not shown).

Referring to FIGS. 2 and 3, the display module 10 may be turned from thelengthwise mode into the widthwise mode or vice versa. The supportingdevice 20 may turn the display module 10 from the lengthwise mode intothe widthwise mode or vice versa.

The supporting device 20 may include the motor. The supporting device 20may turn the display module 10 by using driving force of the motor.Accordingly, the display module 10 may be automatically turned bydriving the motor without the need for the user manually turning thedisplay module 10.

According to the disclosure, the holding device 100 may hold the mobiledevice 10 even when the display module 10 is positioned in the widthwisemode. In other words, the holding device 100 may hold the mobile device2 to prevent the mobile device 2 from being decoupled from the holdingdevice 100 even when the display module 10 is positioned in thewidthwise mode. Accordingly, regardless of positioning of the displaymodule 10, the mobile device 2 may be put onto the display module 10.

The user may selectively position the display module 10 in thelengthwise mode or the widthwise mode, and the display apparatus 1 mayprovide mirror mode, mirroring, or casting in each of the lengthwisemode and the widthwise mode.

In an embodiment of the disclosure, when the mobile device 2 is put ontothe holding device 100 a while a widthwise image is reproduced in themobile device 2, the display module 10 may be positioned in thewidthwise mode. When the display module 10 is already positioned in thewidthwise mode, the display module 10 may not be turned even when themobile device 2 is put onto the holding device 100. When the mobiledevice 2 that is reproducing a widthwise image is put onto the holdingdevice 100 while the display module 10 is positioned in the lengthwisemode, the display module 10 may be turned into the widthwise mode fromthe lengthwise mode. This may enable early detection of the user'smirroring or casting intention and increase user convenience.

As shown in FIGS. 1 to 3, the speaker 30 may be placed below the displaymodule 10. The speaker 30 may be arranged not to be covered by thedisplay module 10 even positioned in the lengthwise mode. This enablesthe speaker 30 to output sound stably regardless of the positioning ofthe display module 10. Furthermore, although the speaker 30 is shown asbeing viewed from outside of the supporting device 20, there may be ametal cover or fabric cover with multiple holes provided in front of thespeaker 30.

In an embodiment of the disclosure, the holding device 100 included inthe display apparatus 1 may be detachably mounted onto the displaymodule 10. The holding device 100 may be mounted onto or detached fromthe display module 10 without any extra member.

The holding device 100 may be mounted on a flank of the display module10 when the display module 10 is positioned lengthwise. The holdingdevice 100 may be mounted on an upper portion of a flank of the displaymodule 10 not to interfere with the supporting device 20 when thedisplay module 10 is turning into the widthwise mode from the lengthwisemode.

Furthermore, unlike what is shown in the drawings, the holding device100 may be mounted on a flank of the display module 10 when the displaymodule 10 is positioned widthwise. In other words, when the displaymodule 10 is positioned lengthwise, the holding device 100 may bemounted on the top of the display module 10.

It is desirable for the holding device 100 to be above the top of thesupporting device 20 when the display module 10 is positionedlengthwise, but it is not limited thereto. Even when the holding device100 is mounted onto the display module 10, it may not interfere withturning of the display module 10. When the holding device 100 isprovided to be accommodated in a space formed between the rear surfaceof the display module 10 and the front surface of the supporting device20, the mounting position of the holding device 100 is not limited. Inthis case, the holding device 100 may be freely mounted at any locationalong the edges of the display module 10.

FIG. 4 shows a holding device of a display apparatus, according to anembodiment of the disclosure. FIG. 5 shows a second supporter drawn outfrom the holding device shown in FIG. 4.

Referring to FIGS. 4 and 5, the holding device 100 may include amounting part 110 provided to be mounted on a frame 15 (see FIG. 1) ofthe display module 10, and a holder 120 rotatably coupled to themounting part 110 and provided to hold the mobile device 2. The frame 15may be provided to form edges of the display module 10.

The frame 15 may include a front surface 15 a, a side surface 15 b, anda rear surface 15 c (see FIG. 10). In an embodiment of the disclosure,the front surface 15 a of the frame 15 may be provided to come intocontact with the screen display region 11. The front surface 15 a of theframe 15 may protrude forward from the screen display region 11 andincline outward from the screen display region 11. The side surface 15 bof the frame 15 may be linked to the front surface 15 a of the frame 15and may incline rearward from the screen display region 11. The sidesurface 15 b of the frame 15 may be larger than the front surface 15 aof the frame 15. The rear surface 15 c of the frame 15 may extend fromthe side surface 15 b of the frame 15 toward the rear side of thedisplay module 10.

The mounting part 110 may be provided to be mounted onto the frame 15 ofthe display module 10. The mounting part 110 may be mounted onto thedisplay module 10 without any extra member, and detached from thedisplay module 10 without any extra member.

The mounting part 110 may include a mounting groove 110 a shaped tocorrespond to the cross-section of the frame 15 of the display module10, and an elastic groove 110 b formed at a distance from the rear sideof the display module 10. Furthermore, the mounting part 110 may includea front supporter 111 to support the front of the frame 15, a sidesupporter 112 to support the flank of the frame 15, a rear supporter 113to support the rear side of the display module 10, and an elasticconnector 114 to connect the side supporter 112 and the rear supporter113. The mounting groove 110 a may be defined by the front supporter111, the side supporter 112, and a portion of the elastic connector 114.The elastic groove 110 b may be defined by the rear supporter 113 andthe rest of the elastic connector 114.

The front supporter 111 may correspond to the front surface of the frame15 to support the front surface of the frame 15.

The rear supporter 113 may come into contactwith a portion of the rear side of the display module 10 to support therear side of the display module 10.

The elastic connector 114 may be provided to connect the side supporter112 to the rear supporter 113. The elastic connector 114 may have acurved cross-section. Specifically, the elastic connector 114 may have aswollen form toward the rear side of the display module 10. The elasticconnector 114 may have substantially constant thickness. With theconstant thickness and curved form of the elastic connector 114, theelastic groove 110 b may be formed between the rear side of the displaymodule 10 and the elastic connector 114. While the front supporter 111and the side supporter 112 may come into contact with the front andflank of the frame 15, the elastic connector 114 may not contact theframe 15 or the display module 10.

With the curved form, the elastic connector 114 may not be broken evenwhen the rear supporter 113 is moved a certain distance in a directionaway from the rear side of the display module 10. Due to the curvedform, elastic limits of the elastic connector 114 may increase. With theincrease in the elastic limits of the elastic connector 114, thedistance for the rear supporter 113 to be moved backwards from thedisplay module 10 may increase.

When the holding device 100 is to be mounted onto or detached from thedisplay module 10, the rear supporter 113 needs to be moved back, inwhich case due to the curved form of the elastic connector 114, theelastic limits of the elastic connector 114 may increase and thedistance for the rear supporter 113 to be moved backwards may increaseaccordingly. Furthermore, the elastic connector 114 may secure theholding device 100 to the display module 10 by applying tension for therear supporter 113 to be moved forwards even after the holding device100 is mounted onto the display module 10. Hence, the holding device 100may secure the display module 10 to the holding device 100 withrestoring force of the elastic connector 14 to restore to its originalstate after the elastic connector 114 is elastically deformed.

The holder 120 may support the mobile device 2 to prevent the mobiledevice 2 from being decoupled from the holding device 100.

Referring to FIGS. 4 and 5, the holder 120 may include a first supporter130 provided to support a side of the mobile device 2 and a secondsupporter 140 provided to support the other side of the mobile device 2.The first supporter 130 may be coupled to the mounting part 110. Thesecond supporter 140 may slidingly move with respect to the firstsupporter 130. The second supporter 140 may be able to slide within acertain range in a direction away from the first supporter 130.Hereinafter, the second supporter 140 sliding in the direction away fromthe first supporter 130 may be expressed as the second supporter 140being drawn out.

As shown in FIG. 4, the first and second supporters 130 and 140 may beprovided to come into contact with each other. As will be describedlater, with no external force applied, the first and second supporters140 may contact each other or may be located closest to each other dueto elastic force of an elastic member. When the first and secondsupporters 130 and 140 are located closest to each other, the distancebetween the first and second supporters 130 and 140 may be set to beless than the left-to-right length of the mobile device 2.

As shown in FIG. 5, with external force applied, the second supporter140 may move away from the first supporter 130. When the first andsecond supporters 130 and 140 are located farthest from each other, thedistance between the first and second supporters 130 and 140 may be setto be greater than common left-to-right length of the mobile device 2.

The user may move the second supporter 140 such that the distancebetween the first and second supporters 130 and 140 becomes wider, andthen place the mobile device 2 between the first and second supporters130 and 140. When the force to the second supporter 140 is releasedafter the mobile device is placed between the first and secondsupporters 130 and 140, the second supporter 140 may move to the firstsupporter 130 due to elastic force and the mobile device 2 may besupported by the first and second supporters 130 and 140.
